MANUFACTURE OF GITS FOR UMBRELLA-FRAMES.

SPECIPICATICN forming part of Letters Patent No. 380,377, dated April 3, 1888.

A nplication filed May 7, 1857. Serial No. 237,463. (No model.) Patented in England November 13, 1885, No. 13,857.

To aZZ whom it may concern.-

Be it known that 1, J AMES WILLIs, a subject of the Queen of Great Britain, residing at Rosendale, Bournemouth, in the county of Hants, England, gentleman, have invented a certain new and useful Improvement in the Method of Producing Gits for the Frames of Umbrellas, Parasols, and Sunshades, (for which I have received Letters Patent in Great Britain, No.13,887,dated November 13, 1885,) of which the following is a specification.

This invention has for its object an improvement in the construction of the frames of umbrellas, parasols, and sunshades, and relates to the method of producing the gitpiece.

I form the gits of drawn steel for paragon or trouglrlike ribs. The steel is drawn as a wire or ribbon, witlrtwo thick sides and a thinner connectingweb between. The pieces for the giis are cut from the wire or ribbon, and they are bent half round to a form to embrace the ribs, which brings the thickened ends of the gits into position to rest upon the edges of the ribs, leaving the interiors of the ribs unencumbered, and not interfering with the construction and working of the joints by which the ribs are connected with the stretchers. When hardened and tempered, the git is put on in its place, and the joint-pin, passing through the thickened ends, secures it.

In the annexed drawings, Figure 1 shows the sectional form of the wire or ribbon of steel from which I make the gils. Fig. 2 shows the section of the metal as it comes from the rolls and before it is drawn down to the section, Fig. 1. Fig. 3 shows the form of the git-pieces cut from the wire or ribbon represented by Fig. 1. Fig. 4 shows the git piece bent I0 the finished form. Fig. 5 shows part of a rib with the git secured to it. Fig. 6 shows part of a rib with the end of a stretcher jointed to the git.

, drawing operation.

The metal of which the gits are to be formed is first rolled to the section shown at Fig. 2-. Afterward the metal is drawn down to the section shown in Fig. 1. The drawing down is effected, alter the manner of wire drawing, through eyes in a hard-steel plate, the metal being from time to time annealed during the From the wire or ribbon formed in this way git-pieces of the form shown at Fig. 3 are then cut, and the git-pieces are pierced with eyes, as the figure indicates. The git-pieces are next bent to the finished form shown at Fig. 4., and are then hardened and tempered to a spring temper. When a gitpiece so formed has been placed upon a rib, it will be held there by its own elasticity and that of the sides of the rib, and also by the subsequent japanning of the rib, and it may be further fixed in any convenient manner, if considered necessary. The git receives the extremity of a stretcher, which is connected to it by a joint-pin or rivet, as represented in Fig. 6.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- The process hereinbefore described for forming the gits for the ribs of umbrellas, parasols, and sunshades, consisting in first drawing a length of wire or ribbon of steel with a thin central portion and thicker sides, then cutting the git-pieces from such wire or ribbon, and finally bending each gitpiece and hardening and tempering it, substantially as described.
